To build a kernel, the package
kernel-source must be installed. Additional
packages, like the C compiler (package
gcc), the GNU binutils (package
binutils), and the include files for the C
are selected for installation automatically by YaST and must be
installed as well.
After installation, the kernel sources are located in
you plan to experiment with different kernels, unpack them in different
subdirectories and create a symbolic link to the current kernel source. Because
there are software packages that rely on the sources being in
/usr/src/linux, maintain this directory as a
symbolic link to your current kernel source. YaST does this automatically.
